Abstract
An apparatus for supplying water or other fluids from a stationary pipe to a moving pipe. The stationary supply conduit has a seam which can be opened and closed somewhat in the fashion of a zipper. An extractor is located inside the supply conduit and has a riser portion which protrudes through an opening in the seam. The extractor is moveable along the length of the supply conduit. Seam opening means create an aperture as the riser approaches while closing means are provided to refasten the seam after the riser has passed. Fluid seals isolate the seam opening from the fluid being carried. The extractor rides on spherical rollers and can include an evacuator tube which removes any water seeping through the seals.
